In the UK, farmers are being encouraged to produce their own biodiesel using waste oil or oil from their own crops with a process that promoters say only takes 20 minutes.

Practical Energy Solutions has developed a process called the Biopot that will transform 75 liters of oil into biodiesel in 20 minutes for under 80 cents per liter. The product costs $3,740, produces up to 375 liters of biodiesel per day and pays itself back in under a year when used at maximum capacity.
